Patented Dec. 8, 1908.

Application flied larch 23, 1908. Serial No. 422,687.

To on whom it may concern:

Be it known that I, CECIL M. COLE, citizenof the United States, residin at Berkele in the county of Alameda an State of Ca fornia, have invented certain new and useful lmnprovements in Paste-Tubes, of which the f0 owing is a specification.

My invention relates to containers and refers especially to those designed for holding adhesives and particularly to aste tubes rovided with an applicator in tli e form of a rush attached directly to the tube.

The chief objects of the im rovements which form the subject matter 0t this application, are :to rovide a container for mucilage or paste aving a brush connected therewlth and an associated nozzle or tube adapted to supply the contained adhesive in suitable quantities to the brush; to furnisha device of the character stated having a,valve or cut-ofl adapted to regulate the supply of a material to the brush, and to produce a construction'that will permit of the ready removal' of the brush and nozzle for the pur pose of cleaning, should the openings become clogged.

Further objects of my invention are to provide a stop for insuring the .prplper registrations of the openings in the noz e and valve; to furnish an index for determining the 10 cation of the valve orifice; to roduce a simple, eflicient and durable mec anism for accomplishing the pur oses in view and to supply a 1paste tube of t e collapsible variety having t e advantages above set forth and that can be manufactured at a comparatively small cost.

As the tendenc of devices of this class is to become clogge from'the natural tendency of the adhesive material to dry quickly, provision is made to kee the brush in proper condition for use by acing a sponge in the protective cover and keeping this moistened water.

ployment of the devices illustrated in the accompanying drawing forming a part of this application, and in-which:

Figure 1 is a side elevation of a container for paste in the form of a tube with rotective cover in place; Fig. 2 is a si ar view with the upper ortion in longitudinal section; Fig. 3 1s a ottom plan view enlarged of the nozzle; Fig. 4 is a top plan view also enlarged of the tube, the cover, brush and brush-retaining sleeve bein removed; Fig. 5 is a longitudinal section 0% the nozzle and brush.

' Referring to the details of the drawing the numeral 10 indicates .the body of a tube, havin its walls 11 of comparatively thin material, and composed of suitable metal to furnish a container of the well known collapsible variety. The walls are contracted at 12 and then continued arallel with the body portion to form a nec 13, closed by a cover plate or valve seat 14, the Walls 12, neck 13 and cover plate 14 being formed integral. The said plate '14 is urnished with a concentrically curved slot 15, and located "diametricall opposite this slot is a feed orifice 16. he surface of the contracted portion 12 immediately surrounding the base of the neck is flattened forming an annular shoulder 17, and the outer surface of the neck is furnished with threads 18.

The neck 13. is surmounted b a nozzle 19, composed of a base 20, conic in sha e and terminating above in a beak or tu e 21. This beak is surrounded by an annular cluster of bristles, forming a brush 22, which, extends considerably beyond the end of the beak. The bristles are held firmly by a band or ferrule 23, beveled on the lower margin to suitabl engage the inclined face of the base 20. he nozzle 19 and attached brush 22' are secured in positionupon the plate 14 by means of a thimble or sleeve 24, contracted at one end by a flange 25 inclined with the body of the sleeve to corres 0nd with the inclination of the outer su ace of the base and having a central 0 ening engaged by the ferrule v23. The sl eve 24 is furnished with internal threads to fit the threads 18 on the neck and the lower margin of the said sleeve engages the annular shoulder 17 to make a tight joint. The arts are so adjusted that when the said s eeve is screwed into contact with the shoulder 17 the flange25 will bear lightly upon the inclined face of the base ho ding it by frictional contact but'permittin the nozzle and attached brush and ferru e to be turned therein. The said. nozzle is furof the base 20., is furnished with a downwardly projecting lug or in 29, preferably formed integral with sai base. This in engages the slot 15, and the ends of the s ot brush in proper condition for a considerable time, but when the device is not in frequent use a farther aid in keepin the brush from drying out is supplied by t e use of a small piece of sponge 31 inserted in the top of the cap and ke t moist with water, the interior of the cap thus becoming a moistening chamber for the purpose stated.

The manner inwhich the parts are assembled'will be understood by inspection of i the views. It may be mentioned, however, that the brush is put together by assembling a tuft of bristles, suited to the purpose, about the beak 21, and securing them in place by the ferrule 23, which fits tightly around the brush its lower margin engaging the inclined face of the base ortion of the nozzle. That art of the brus clamped between the ferru e and the beak may be filled with a suitable adhesive not affected by moisture, such as shellac or rubber cement, thus insuring a more durable construction of the brush. When the tube 10 is formed the lower end is leftopen and through this opening the tube is filled with paste andthe end afterward closed. I

The details of construction having been prevent rapid evaporation and tend to keep the will only be necessary to remove the cover and turn the brush until the movement is sto ped by the engagement of the pin 29 wit the end of the slot 15. The tube is now inverted and a suflicient the liquid lpaste will flow .throug the duct 26 to suppiyl the brush.

Having t us described my invention what I claim, is:-

1. In a device for applying adhesives, the combination with a container and .a perforated cover-plate therefor, of a nozzle, a perforated conical base for the nozzle, a lug on said base engaging a slot in the coverplate, a sleeve adapted to hold said base on uantity of said cover-plate and a brush embracing the nozzle.

2. In a device for applying adhesives, the combination with a container and a perforated covermade integral with said container, of a nozzle comprising a perforated conical base engaging said cover and a beak integral with said base, a lug on the base enga ing a slot in the cover, a sleeve adapted to ho (1 said base on said cover and a brush surrounding the nozzle.

In testimony whereof I afiix my signature in the presence of two witnesses.
